Gmail Human in Loop Stopped Worked

Questions
1

Don’t you love it when things stop working for “no reason”? My workflow runs until it gets to the Gmail Send & Wait node. I receive the email, launch the review page and click ‘Submit’. At that moment, an error is triggered, BUT n8n NEVER gives me any error information. It’s incredibly frustrating. I’m wasting hours on this. The useless error message I receive: Workflow execution had an error.
No kidding. :slight_smile:

Not sure if it’s a problem with the webhook URL, which is different from public URL.

I barely have any hair left to pull out, so any help would be greatly appreciated. Thanks!

n8n version: 1.89.2

Hi, are you running a self-hosted instance? Did you upgrade recently? Did you try to test with another send and wait node? Did you try to rebuild the workflow (not copy paste)

I’m running n8n on Railway. I have other workflows that work fine with these nodes. Didn’t upgrade. A big problem with these clunky Send & Wait nodes is lack of error info. When you look in Executions…nothing. It’s a joke. Hopefully, they fix this. It make troubleshooting extremely time consuming.
